Beginning in FY20, ECCC-RC transitioned from a four phase course administered by the US Army Engineer School (USAES) to a three phase course administered by USAES with a course prerequisite administered by the Combined Arms Center (CAC).  The ECCC-RC course content was not impacted by this change and any courses completed during FY19 or earlier are still accepted as equivalents for the current phase construct as outlined in the document provided through the link below.
